,-WAGONBODY HOIST.

SPECIFICATION forming part of Letters Patent No. 721,832, dated March 3, 1903. Application filed September 5, 1902. Serial No. 122348- (No model.)

T all whom it 11a/ty concern:

Be it known that I, MARK PLUMMER, a citizen of the United States, residing at Mineralspring, in the county of Barry and State of Missouri, have invented a new and useful Wagon-Body Hoist., of which. the following is a specification.

This invention relates to Wagon-body hoists.

The object of the invention is to provide a simply-constructed, thoroughly-efficient, 'and durable form of device for the purpose specified in which the number of parts shall be reduced to the minimum and in which the combination and arrangement thereof shall be effected in a manner best calculated to afford ease and certainty of operation.

A further object is to dispense with the employment of any clamping means for attaching the device to the wagon-body.

With these and other objects in view, as will appeal' as the nature of the invention is bet-ter understood, the same consists in the novel construction and combination of parts of a wagon-body, as will be hereinafter fully described and claimed.

In the accompanying drawings, forming a l part of this specification, aud in which like numerals of reference indicate corresponding parts, there is illustrated one form of embodiment of the invention capable of carrying the same into practical operation, it being understood that the elements therein eX- hibited may be varied or changed as to shape, proportion, and exact manner of assemblage without departing from the spirit thereof, and in the drawings- Figure l is a view in perspective, exhibiting the device of this invention operatively associated with the wagon-body and also the derrick or support for the body. Fig. 2 is a perspective view of the derrick. Fig. 3 is a sectional detail view ofa portion of the wagonbody, showing more particularly the manner in which the hoisting device is Aassociated therewith. Fig. 4 is a perspective detail view of the hoisting device. y Y

The hoisting device (more particularly shown in Figs. 3 and 4) comprises a framebar 1, having its lower portion bent at right angles to its length to presenta sill-engaging hook 2, the terminal of which is formed into a toe 3, designed by engagement with a staple or shackle 4, secured to the cleat 4 of the wagon-body, to'preven't accidental separation of the frame-bar from the wagon-body when once associated therewith. The framebar has rigidly secured to it intermediate ofits ends a spindle 5, upon which is mounted a drum 6, having the usual flanges '7 and 8, the periphery of the latter of which is toothed to present a ratchet-wheel to be engaged by a pawl 9, carried bythe frame-bar. The upper endof the frame-bar presents a` handle l0, by which to facilitate handling of the same when it is to be associated with the body. On the outer side of the ange 7 is arranged a crank l1, which is preferably integral with the flange, thus toreduce the number of parts of the device to a minimum. The drum is held from disconnection with the spindle by a pin l2, between which and the flange is interposed a washer 13, as usual.

By the provision of the staple or shackle 4, which will be permanently'associated with the cleat, clamping devices such as are usually employed for holding the frame-bar assembled with the cleat are rendered unnecessary, as it will be seen when the wagon-body is lifted that all the weight is borne by the hook 12, and this will be held positively against disconnection from the staple or shackleby the toe 3. The hoisting device,

in effect, consists of two principal partsnamely, the frame-bar with the spindle rigidly secured thereto and the drum with the handle rigid or integral therewith. The number of parts of the apparatus is thus reduced to the minimum and will not only operate to prevent danger of breakage or derangement in use, but will also materially lessen the cost of production of the device.

The drum has secured to it an eye 14, wit which is connected one end of a hoisting-rope l5, which is adapted4 to pass through overhead pulleys, which may be suspended from the joists or rafters of the barn or shed in which the wagon is placed,the free end of the rope being in this instance tiedY around the end of the body, as at 16. As a matter of further and specific improvement and to provide a ready means of turning the Wagonbody to one side should it be so desired there is provided a novel form of derrick comprising an upright 17, which may be rigidly held ICO in any preferred manner in vertical position and has connected with it two outwardly-extending arms 18, provided with openings to be engaged by pintles 19, arranged at the terminals of a bar 20. Arranged at a point near the upper end of the bar is a cross-piece 21, at the terminals of which are arranged grooved sheaves 22, over which the rope 15 passes. The cross-piece is supported from the bar 2O by horizontal diverging arms 23, secured at their inner terminals to the bar and at their outer terminals to the cross-piece, said arms being braced by inclined struts 24. By the provision of this derrick after a wagonbody is lifted it may be swung to one side, thus to move it out of the way of the runninggear or to cause it to occupy less room in a shed or the like.

In the operation of the device the rope is passed over the sheaves 22, and one end is secured in any suitable manner around the wagon-bottom, the other end being secured in the eye 14 of the drum. The hook is then inserted through the staple or shackle 4 and the frame-bar pushed up against the end of the body, and upon the crank being turned the rope will be wound upon the drum,causing the lifting of the body, the pawl 9 operating to hold the body poised at the desired height.

While the device of this invention is exceedingly simple of construction, it will be found thoroughly efcient in use for the purposes designed and maybe manufactured and sold at a price to place it within the reach of all those desiring such an article.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, s-

1. A device of the class described, comprising a frame-bar provided with means for engaging a portion of a Wagon-body, a spindle rigid with the bar, a drum mounted on the spindle and having integral flanges, one of which is provided with ratchet-teeth and the other with a crank integral therewith, and a paw] carried by the bar to engage the ratchetteeth.

2. A device of the class described, comprising a frame-bar having its upper portion provided with ahandle and its lower portion with a hook terminating in a downturned toe, a spindle rigidly connected with the bar intermediate of its ends, a drum mounted on the spindle and provided with integral flanges one of which is provided with ratchet-teeth and the other with a crank integral therewith, and a pawl carried by the bar to engage the ratchet-teeth.

3. The combination with a wagon-body having one of its cleats provided with a staple or shackle, of a hoisting device comprising a frame-bar having its lower terminal formed into the hook to be inserted through the shackle and terminating in a toe to prevent accidental separation of the hook from the shackle, a spindle rigidly connected withl the bar intermediate of its ends, adrum mounted on the spindle and having integral flanges, one of which is provided with ratchet-teeth and the other with a crank integral therewith, a pawl carried by the bar to engage the ratchet-teeth, and a handle constituting the upper terminal of the bar to facilitate handling of the device.

In testimony that I claim the foregoing as my own I have hereto aiixed my signature in the presence of two witnesses.
